In the 60s of the last century, six gold coins were unearthed at Jinshi, Hunan, China. They are said by the local museum to be Indian coins struck by the Delhi Sultanate (1206-1526). The obverse apparently carries the title and name of the ruler while the reverse is thought to be written in a form of Arabic script. So far no one has been able to read the inscriptions on the reverse. The museum is offering a reward of 10,000 yuan (US$1,531.36) to anyone who can read the inscriptions.
